- In perception, a
*discrete entity* is something that can be perceived individually and not as connected to, or part of something else. - In topology, a branch of mathematics, a
*discrete space* is a topological space in which all sets are open, and a *discrete set* is a set of isolated points. - In discrete mathematics, without notion of continuity, a discrete set is a countable set; this concept is also important for combinatorics, probability theory, and statistical theory.
- In statistics a discrete random variable defines a particular type of variable (in contrast to a continuous random variable).
- In discrete mathematics and in theoretical computer science, the abstract world is usually modeled as a
*discrete space* with *discrete time*. - In electrical engineering,
*discrete* means having separate electronic components, such as individual resistors and inductors. This is the opposite of integrated circuitry. - In audio engineering,
*discrete* means having separate and independent channels of audio, as opposed to matrixed stereo or quadrophonic, or other multi-channel sound. - A
*discrete signal* in information theory and signal processing - In music, a
*discrete pitch* is one with a steady frequency, rather than an indiscrete gliding, glissando or portamento, pitch. Discrete is *not* the same thing as discreet. PSYCHOLOGY In psychology and the cognitive sciences, perception is the process of acquiring, interpreting, selecting, and organizing sensory information. ...
Topology (Greek topos, place and logos, study) is a branch of mathematics concerned with spatial properties preserved under bicontinuous deformation (stretching without tearing or gluing); these are the topological invariants. ...
In topology and related fields of mathematics, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense. ...
Topological spaces are structures that allow one to formalize concepts such as convergence, connectedness and continuity. ...
In topology and related fields of mathematics, a set U is called open if, intuitively speaking, you can wiggle or change any point x in U by a small amount in any direction and still be inside U. In other words, if x is surrounded only by elements of U...
In topology, a point x of a set S is called an isolated point, if there exists a neighborhood of x not containing other points of S. In particular, in an Euclidean space (or in a metric space), x is an isolated point of S, if one can find an...
Discrete mathematics, also called finite mathematics, is the study of mathematical structures that are fundamentally discrete, in the sense of not supporting or requiring the notion of continuity. ...
In mathematics the term countable set is used to describe the size of a set, e. ...
Combinatorics is a branch of mathematics that studies collections (usually finite) of objects that satisfy specified criteria. ...
Probability theory is the mathematical study of probability. ...
The theory of statistics includes a number of topics: Statistical models of the sources of data and typical problem formulation: Sampling from a finite population Measuring observational error and refining procedures Studying statistical relations Planning statistical research to measure and control observational error: Design of experiments to determine treatment effects...
A graph of a bell curve in a normal distribution showing statistics used in educational assessment, comparing various grading methods. ...
In mathematics, a random variable is discrete if its probability distribution is discrete; a discrete probability distribution is one that is fully characterized by a probability mass function. ...
In computer science and mathematics, a variable (sometimes called a pronumeral) is a symbol denoting a quantity or symbolic representation. ...
By one convention, a random variable X is called continuous if its cumulative distribution function is continuous. ...
Discrete mathematics, also called finite mathematics, is the study of mathematical structures that are fundamentally discrete, in the sense of not supporting or requiring the notion of continuity. ...
Computer science (informally, CS or compsci) is, in its most general sense, the study of computation and information processing, both in hardware and in software. ...
In topology and related fields of mathematics, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense. ...
Discrete time is non-continuous time. ...
This article treats electronics engineering as a subfield of electrical engineering, though this is not typical use in some areas. ...
The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. ...
